Just how hot will it get? Well, apparently, the mercury will rise to a level where the Microsoft Surface Pro 3 will automatically kick in its failsafe action, that is the safety mode which would turn everything off until the Surface Pro 3 has sufficiently cooled down. Do bear in mind that this not an isolated case, as at least a quartet of units have already shown off such excessive heat as evident in the Microsoft Answer forums so far.
While the Core i7, being Intel’s high-performance range of CPUs, will obviously run at a higher heat level compared to its slower Core i5 and Core i3 siblings, to have it shut down because it is too hot is definitely a fail. Hopefully Microsoft will be able to fix this particular issue, and in good time, too.
